Here is one of Bob Dylan's most famous songs. It's called "The Times They Are a-Changin'"
Watch the clip and read the lyrics below

Come gather ’round people
Wherever you roam
And admit that the waters
Around you have grown
And accept it that soon
You’ll be drenched to the bone
If your time to you is worth saving
Then you better start swimming or you’ll sink like a stone
For the times they are a-changing

Come writers and critics
Who prophesize with your pen
And keep your eyes wide
The chance won’t come again
And don’t speak too soon
For the wheel’s still in spin
And there’s no telling who that it’s naming
For the loser now will be later to win
For the times they are a-changing

Come senators, congressmen
Please heed the call
Don’t stand in the doorway
Don’t block up the hall
For he that gets hurt
Will be he who has stalled
There’s a battle outside and it is raging
It’ll soon shake your windows and rattle your walls
For the times they are a-changing

Come mothers and fathers
Throughout the land
And don’t criticize
What you can’t understand
Your sons and your daughters
Are beyond your command
Your old road is rapidly aging
Please get out of the new one if you can’t lend your hand
For the times they are a-changing

The line it is drawn
The curse it is cast
The slow one now
Will later be fast
As the present now
Will later be past
The order is rapidly fading
And the first one now will later be last
For the times they are a-changing
